Abstract
The measuring system comprises a vibration-type measuring sensor, a sensor housing, a magnetic-field detector, and measuring-system electronics electrically coupled both to an oscillation exciter and to oscillation-sensing devices of the measuring sensor. The measuring sensor is inside the sensor housing and the magnetic-field detector is outside the sensor housing. The magnetic-field detector is designed to convert changes in the magnetic field into a magnetic-field signal having an amplitude dependent on a magnetic flux through the magnetic-field detector and/or on an area density of said magnetic flux. The measuring-system electronics are designed to determine, on the basis of oscillation measurement signals of the measuring sensor, the mass-flow-rate measurement values representing the mass flow rate and to at least qualitatively determine, on the basis of the magnetic-field signal, whether an external magnetic field is established inside the measuring sensor.
